F EY WATERPROOF SHEET AND TIE AND MASONRY WALL WATERPROOFED THEREWITH Filed Oct. 15, 1951 INVENTOR. F. C. BAILEY ATTORNEY 2,791,117 y'Patented May 7, 1957 WATERPROOF SHEET AND AND MASNRY This invention relates to building construction and r'more particularly to the waterproofing of the side walls f of' a building or the provision of a. waterproof barrier within such walls. Y l 4 Heretofore efforts have been made to waterproof buildings as Well as to provide the necessary strength. of construction, however such prior structures have not been fully satisfactory for various vreasons including the fact that such walls were too fragile or lacked durability, required excessive time and effort in their construction and consequently were too costly, and also becausev of their failure to accomplish the desired result.

It is an object of the invention to provide building construction protected against the weather, including simple and effective means produced of readily available materials'applicablewith mini-mum eiort during the erection of a wall of conventional construction, to bar the 'passage of water or the like.

Another object of the invention is to`v provide relatively simple, inexpensivev waterproofV sheeting preeut to appropriate length and width to fit conventional brick and block structure and with attaching clips by means of which the sheeting may be secured in position.

Another object of the invention is to provide weather proof sheeting with mounting elements which perform an additional function of securing together the dual portions of a wall, and which requires no particular additional space in the shipping and storing of same.

Further objects and advantages of the invention will be apparent from the following description taken in conjunction with the accompanying drawing, wherein:

Fig. 1, a perspective, partly in section, of a wall illustrating one application of the invention;

Fig. 2, an enlarged perspective of one embodiment of the invention partly in section, with the mounting clip in folded position and with phantom lines illustrating the extended position of the same;

Fig. 3, a perspective with parts in section of a modified form of clip in operative position; and

Fig. 4, a perspective further illustrating the clip of Fig. 3.

Briey stated the invention comprises building construction or wall structure including sheets which are adapted to be applied to a wall or other part of a structure or form a barrier to the passage of moisture as for example between the two parts of a wall, commonly designated veneer, and which consists of an inner structure of large blocks and an outer structure or veneer of smaller blocks such as for example, bricks.

The sheets between the larger blocks and the veener blocks prevent the passage of moisture and in order to easily mount these sheets and to tie together the inner and outer portions of the wall structure in compliance with the building codes the U-shaped clips are fastened over the upper portions of the sheets by means of vrivets or other fastening elements and the legs of these U-shaped glips can be bent outwardly in opposite directions and 2 have their ends upturned for anchorage in the mortar ,between the blocks used in the wall or other structure.

With continued reference to thev drawings, the present invention may be employed in various ways as for example between the interior and exterior portions oa composite wall and when applied between the esame will perform the multiple functions of forming a bar rer to lthe passage of moisture, a hanger or support for the material forming the; bari-ier, and thev important function rin compliancel with building codes by binding or tying together the interior and exterior portions ofl the structure.

The invention contemplates utilization of variosmaterials and is illustratedl in connection with awafll of masonry having a footing with an interior wa1l of relatively large blocks 1l of concrete,j cindersvor othei composition wi'than outer wall formingthe facing or veneer of the building composed of smaller blocks 12 which may be of brick,y cement, stone or other substance. These large and small blocks ot the inner and outer wall sections are joined or boundv together Vinto a unitary construction by means of mortar or the likel, a 4weep hole or drainage channel 14 beingy provided beneath the outer wall section.

In the construction o f the wall the inner wall section isY built up of rows or tiers of two or more yofthe large blocks 1l tothe back of which is applied the waterproo'ng barrier in the form of a membrane or sheet 15 `which may be of plastici er other' desired waterproofing composition and of a size fof ,eenvenient handling and shipping', preferabIy corresponding to a prescribed ber 'of bloc-:ks in both height and width.

In View of the fact that the inner and ilte Wall sections may not be intimately united and any space be'- tween them is likely to increase due to dryingv of the niater-ials and settling, it is desirable to have some means of supporting the sheets 15. In order to accomplish this result U-shaped spring clips 16 are fitted in spaced relation over the upper edges of the sheets 15 and the parts are united in spaced relation to the edge of the sheet by means of a fastening element 17. In this condition as illustrated in Fig. 2, the sheets and clips are at and may be stacked during storage and shipment. When applied the free ends of the clips may be bent outwardly to form anchoring extremities 18 for location between the blocks of the inner and outer sections of the wall and are anchored by the mortar in the construction of the wall. After the blocks 11 along the inner wall are in place and sheets are mounted on the outer face of such blocks, the blocks 12 forming the outer wall section are applied until both sections are substantially the same height thereupon the inner wall section and outer wall sections are alternately built up with the waterproof sheeting between the same and with the joints lapped as disclosed.

lf desired in order to secure the zlower edge of a sheet to the sheet beneath it, the clips on the lower sheet may be provided with tongues 19 as shown in Figs. 3 and 4.

The inner wall section forms a base for a nishing coating 20 on the interior of the building, such iinish may be applied directly to the block as illustrated in Fig. l or in any other desired manner.

It will be understood from the foregoing that the pres-- ent invention is simple and inexpensive, can be easily stored and shipped, readily applied, provides an airtight structure, and by its use the passage of moisture from the inner portion to the outer portion of a wall is prevented at the same time the wall is improved in char# acter by having its inner and outer sections tied together in compliance with building codes. 1

It will be obvious to those skilled in the art that various changes may be made in the invention without departing from the spirit and scope thereof, and therefore, the invention is not limited by that which is shown in the drawings and described in the specification but only as indicated in the appended claims. A

-What is claimed is:

1.. Building material for waterproofing and tying together wall portions comprising exible elongated moisture barrier sheet of waterproof material for application between an inner Wall and an outer wall to prevent moisturc from passing through the outer wall into the inner Wall, said `sheet having a pair of generally parallel side edges, aplurality of U-shaped clips formed of bendable strip material arranged in spaced relation along one of said side edges of saidy sheet, each of said clips having its bight portion seated against said one side edge with Ithe legsof each clip arranged substantially perpendicular to said one side edge and embracing the adjacent surface portions of said sheet, a fastening element extending between and secured to the legs of each clip and passing through the sheet at a point spaced from said one edge thereof, each fastening element being spaced the same distance fromsaid one side edge as the other of said fastening elements, said legs of the strip material extending beyond .the location of said fastening element and toward the other side edge of the sheet whereby the elongated sheet with the clips tixedthereon may be rolled for storage or shipment.

2. The invention according to claim l in which a tongue portion is struck from one of the'legs of each clip adjacent the fastening element and is bendable `at an angle to its leg and bendable about a point spaced beyond the fastening element to provide a tongue for grippingengagement with an adjacent barrier sheet.

3. Masonry building construction comprising inner and outer wall portions with a longitudinal joint separating .the wall portions, an elongated moisture barrier sheet of waterproof material positioned between said inner and 4 outer wall portions to prevent the passage of moisture from the outer wall portion to the inner wall portion and g covering any joints in said wall portions, said sheet being of a size to provide moisture proong over an extended area, a plurality of supporting means fixed to the upper edge portion of the sheet material and spaced there along, each supporting means including a strip of material of inverted U-shape with lateral extensions on the free ends of its legs with the legs embracing the upper edge portion of said sheet and the bight of the supporting means seated against the edge thereof, the lateral ex tensions on each side being embedded in the adjacent inner and outer wall portions for locking said inner and outer wall portions together to form a rigid wall, a fastening element extending between the legs embracing the upper edge portion of said sheet and through the sheet material and iixedly securing said supporting means on the edge portion of said sheet whereby the sheet will be maintained in a definite relation with re,- spect to the wall and the said upper edge portion of the sheet will project above the lateral extensions to provide for overlap by an adjacent sheet of waterproof material wherebya waterproof seal is maintained between said linner .and outer wall portions, and a tongue on each supporting means projecting upwardly from one of the lateral extensions and spaced from the adjacent leg a distance corresponding to the thickness of the barrier sheet to maintain such adjacent barrier sheet in fixed relation to said first mentioned barrier sheet.
